Ferritic Nitrocarburize(FNC),这是一种热处理要求，怎么翻译？

铁元素氮碳共渗处理.
Gaseous and liquid salt bath ferritic nitrocarburizing processes diffuse carbon and nitrogen into the surface of ferrous materials at a temperature within the ferritic phase range, typically around 579C (1075F). 气体和盐浴的铁索体氮碳共渗工艺 是在铁索体阶段时某个温度（一般在579C）通过碳和氮扩散渗入铁索体材料的表层来获得需要的性能。The gaseous versions commonly use a batch furnace atmosphere consisting of equal portions of ammonia and endothermic carrier gas. 气体工艺通常采用单炉气氛，这种气氛主要包括等量的氨和吸热式载气。 Liquid processes utilize various proprietary high and low cyanide containing molten salts液体工艺采用几种含有高含量和低含量的氰化物熔盐的熔液 . After treatment the part is quenched in water, oil or molten salt. 渗完之后零件进行水淬、油淬或盐浴淬火Each process must result in the formation of a wear resistant surface compound layer, "white layer", and an underlying diffusion zone containing dissolved nitrogen. 每种工艺都要形成耐磨的表面化合物层，“白亮层”和往下的含有溶解氮的扩散层区域。

以铁酸盐为主要成分的东西
